About our facade sealing in Upton
We don’t install glazing systems or replace glass. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters, using sealants classified for facade or glazing use. We work on cladding panel joints, coping and flashing joints and shopfront frames, and the usual reasons a site gets in touch are failed seals around shopfront and entrance frames and leaks at window and door perimeters. One point of contact handles commercial sealant work in Upton from the first photos to the final walk-round, for single jobs and planned programmes alike.
On a small site around Upton, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we will time the work so nothing waits on us.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Cost factors for facade joints
These are the things that shape the price:
- Travel to remote or island sites
- How accessible the joints are
- Joint width, depth and condition
- The total length or number of joints
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.
Details that help us quote
However big the job, the same details help:
- The postcode of the building
- Access details, including height
- Clear photographs of the problem areas
- Whether the building will be occupied during the work
The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or speak to us on 01277 525 020 or email drawings and photos to discuss it first.
General trades versus a specialist
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
From enquiry to sign-off
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a job in Upton, the main thing is a clear picture of the work. A fixed quote follows.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
Getting the site ready
- Share your working hours and any access restrictions
- Explain the parking and delivery arrangements
- Make sure the joints can be reached

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
Advice
Leave it or put it right?
Failed joints let in more than water: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. In a smaller place such as Upton, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

New build and refits around Upton
Upton is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager. The area within 2 miles of Upton holds a good number of hotels. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.
When a school such as St Mary's Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Work at a hotel such as Skyways Hotel, 0.9 miles to the east of Upton, tends to be programmed around bookings, mastic included.
Upton is about 1 mile south-east of Slough, in Slough. We cover commercial sites throughout Upton, for single jobs and planned programmes alike. Our Slough coverage takes in 11 places. Our Reading page has more on work in that area (17 miles or so).
If you need facade sealing in SL1, SL3 and SL2, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

Questions we’re asked in Upton
Is Upton off your patch?
Not at all. Upton is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Would you work within a site like Upton Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
What hours do you work?
Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Will you come and look before quoting?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
When to call us in Upton
Product choice matters: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.
Things that typically lead to an enquiry:
- Weathered joints at frame-to-structure perimeters
- Failed sealant on precast panel joints
- Water coming in around window frames
- Staining on stone next to old sealant
Further education sites such as Slough & Langley College (2 miles east of Upton) are extended and refurbished from time to time, with mastic often programmed into the summer break.
What your quote should include
- Will CSCS-carded applicators be on site?
- Will RAMS and insurance details be available?
- How joint depth will be controlled
- How the joint faces will be prepared and primed
